The official Dropbox app for iOS is perfectly fine, but the folks at Tapwings thought they could improve it. With the new Boxie ($2 until Oct. 23, then $3) for iOS 7, they have...for the most part.\n\tBoxie aims to "prettify your Dropbox." It\u2019s a nice-looking and easy-to-use app with a clean, iOS 7-friendly interface. (The software only supports iOS 7 or later.) Setup is simple. One tap, and the app connects to your Dropbox account. You press down on a file and drag it into its new home to switch folders.\n\tBoxie does things Dropbox for iOS doesn\u2019t. You can sort files by name, date (earliest or latest), size and file type. I love that. By comparison, the Dropbox iOS app only lets you sort by A-Z or newest-oldest. It\u2019s worth noting, however, that Boxie\u2019s sorting options apply to all your Dropbox files viewed in the app. The official Dropbox app lets you vary the file sorting from one folder to the next.\n\t(File sorting in Dropbox, left, vs. Boxie, right)\n\tUnlike Dropbox for iOS, Boxie also lets you easily view a list of revisions for specific files and then restore the one you want. Boxie\u2019s search function lets you search folders, subfolders or all of Dropbox. The official Dropbox app only offers a Dropbox-wide search if you\u2019re at your Dropbox folder\u2019s root level. Otherwise, searches are confined to the folders you\u2019re in.\n\tHowever, Boxie's offline file-access feature didn't work for me. (Dropbox for iOS doesn\u2019t currently offer this feature at all.) After marking a folder for offline viewing, I turned on Airplane Mode, then tried to access the files in that folder. The folder showed no items, and I received a network error message. I tried this a handful of times, with different folders, to no avail.\n\tOn the flip side, the official Dropbox app can automatic upload your camera images. Boxie doesn\u2019t do this, but the developer says it will in the future.\n\tAlso worth mentioning: Boxie is currently only optimized for iPhone and iPod touch. iPad support would be ideal (and is promised in the future), because most people are more likely to work on documents on a tablet than on a smartphone. Dropbox is optimized for iPads.\n\tBoxie isn\u2019t currently available for Android, either. There\u2019s an official Dropbox Android app, as well as third-party Android apps that integrate with Dropbox. Folder Downloader for Dropbox, for instance, lets you download Dropbox folders to your Android device.\n\tIs Boxie worth $2 when the Dropbox app is free? Yes, if you use Dropbox a lot on your iPhone or iPod touch. Otherwise, wait until there\u2019s an iPad-optimized version.
